Muslim

Abdullah bin Shaqiq reported: I said to'A'isha (Allah be pleased with her): Did the Apostle of Allah (ﷺ) observe fast for full one month besides Ramadan? She said: I do not know of any month in which he fasted through-out, but that of the month of Ramadan and (the month) in which he did not fast at all, till he ran the course of his life.

'Abdullah bin Shaqiq reported: I said to 'A'isha (Allah be pleased with her): Did the Messenger of Allah (ﷺ) observe fast during a month? She said, I do not know of any month in which he fasted throughout except Ramadan and (the month) in which he did not fast at all till he ran the course of his life. May peace be upon him.

Abdullah bin Shaqiq reported. I asked 'A'isha (Allah be pleased with her) about fasting of the Messenger of Allah (ﷺ) . She said: He used to observe fast (at times) so continuously that we said: He has fasted, he has fasted. And (at times) he did not observe fast (for days) and we began to say: He has abandoned fasting, he has abandoned fasting. She said: I did not see him observing fast throughout the whole of the month since he arrived in Madinah, but that of Ramadan.

A hadith like this has been narrated on the authority of'Abdullah bin Shaqiq but in the chain of transmitters no mention is made of Hisham and Muhammad.

'A'isha, the Mother of the Believers (Allah be pleased with her), reported that the Messenger of Allah (ﷺ) used to observe fasts (so continuously) that we said that he would not break, and did not observe (them) till we said that he would not fast: and I did not see the Messenger of Allah (ﷺ) completing the fast of a month, but that of Ramadan, and I did not see him fasting more in any other month than that of Sha'ban.

Abu Salama reported: I asked 'A'isha (Allah be pleased with her) about the fasting of the Messenger of Allah (ﷺ) . She said: He used to observe fast (at times so continuously) that we said: He has fasted (never to break), and he did not observe fast till we said: He has given up perhaps never to fast, and I never saw him observing (voluntary fasts) more in any other month than that of Sha'ban. (lt appeared as if) he observed fast throughout the whole of Sha'ban except a few (days).

'A'isha (Allah be pleased with her) reported: The Messenger of Allah (ﷺ) did not observe fast in any month of the year more than in the month of Sha'ban, and used to say: Do as many deeds as you are capable of doing, for Allah will not become weary (of giving you reward), but you would be tired (of doing good deeds); and he also said: The deed liked most by Allah is one to which the doer adheres constantly even if it is small.

Ibn Abbas (RA) (Allah be pleased with both of them) reported: The Messenger of Allah (ﷺ) did not fast throughout any month except during Ramadan. And when he observed fast (he fasted so continuously) that one would say that he would not break (them) and when he abandoned, he abandoned (so continuously) that one would say: By Allah, perhaps he would never fast.

This hadith has been narrated on the authority of Abu Bishar with the same chain of transmitters (with a slight variation of words and these are), that he (the narrator) said: "During any month continuously since he came to Madinah."

'Uthman bin Hakim al-Ansari said: I asked Sa'id bin Jubair about fasting In Rajab, and we were then passing through the month of Rajab, whereupon he said: I heard Ibn 'Abbas (Allah be pleased with both of them) as saying: The Messenger of Allah (ﷺ) used to observe fast (so continuously) that we (were inclined) to say that he would not break (them) and did not observe them so continuously) that we (were inclined to say) that he would not observe fast.

The same hadith as the previous hadith has been transmitted through another chain.

And narrated to me Zuhayr ibn Harb and Ibn Abi Khalaf, they said: Rawh ibn ‘Ubadah narrated to us, Hammad narrated to us, from Thabit, from Anas, may Allah be pleased with him. And narrated to me Abu Bakr ibn Nafi‘—and the wording is his—Bahz narrated to us, Hammad narrated to us, Thabit narrated to us, from Anas, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him: "He would fast until it was said, 'He has fasted, he has fasted,' and he would break his fast until it was said, 'He has broken his fast, he has broken his fast.'"
